Thred Free Digitizing Program-Need help

abbie

Hello,
I was wondering if anyone has used Thred Free digitizing program? I have been doing machine embroidery for many years and can do editing with my old Viking software. I found this free program online complete with manual and HELP section but there are a few things that just dont seem to make sense. Is anyone familiar with this program or good at figuring out the "whys" of settings? I would appreciate any help.

Here's a link to the website.
